This is my sons BK sub. He's not been able to use it in his apartments, so i have it now so i can sell it for him. Its about 5yrs old, its hardly been used and is mint - there are no marks on it - indistinguishable from new i'd say. The finish is satin black.

In terms of performance, i use a BK Gemini II for the TV and when i tried it, it was obvious the 400 is far superior in every respect; its super powerful and everything is effortless.

Its a downward firing sub and the (Peerless) woofer is mint too. Have a look at the BK Website for the full specification; there's a few good reviews out there too.

My son would like £300 for it.

As u can see from the pictures i have packed it carefully in its original packing and added more bubble wrap. Now heres the thing... Its very heavy in that box. For that reason this is collection only. I really do not want to use a courier.

Any questions then please PM me and I'll be happy to help.

Cheers Richard
